Anwendungshinweise

  • AN-1798 Designing with Electro-Chemical Sensors (Rev. C)
    PDF, 62 Kb, Revision: C, Datei veröffentlicht: May 1, 2013
    As early as 1950, electro-chemical sensors were used for oxygen (gas) monitoring; however, with increasing concerns about personal safety, the demand for portable electro-chemical sensors has dramatically increased. Today, electro-chemical sensors are commonly used in portable equipment todetect different toxic gases.
  • AN-1852 Designing With pH Electrodes (Rev. A)
    PDF, 115 Kb, Revision: A, Datei veröffentlicht: May 1, 2013
    A pH electrode measures hydrogen ion (H+) activity and produces an electrical potential or voltage. Theoperation of the pH electrode is based on the principle that an electric potential develops when two liquidsof different pH come into contact at opposite sides of a thin glass membrane. This was originallydiscovered in 1906 by Max Cremer [1]. His discovery laid the foundation for Fritz Habe
